Rufous-throated Antbird Gymnopithys rufigula

Medium-sized antbird of rainforest understory, almost always encountered near swarms of army ants, which it follows to pursue insects flushed by the ants. No similar species in range; key field marks are pale legs and striking bare eyering, which appears white in dim forest understory. Frequently seen perched on vertical stems within a meter of the ground. Usually heard prior to being seen; gives low churring calls while foraging and a sharp doubled note when chasing other birds.
